Remote calibration
Use the following procedure to perform remote calibration by sending SCPI commands over
the IEEE-488 bus or RS-232 port. The remote commands and appropriate parameters are
separately summarized for each step.
Remote calibration commands
Table 2-5 summarizes remote calibration commands, while Table 2-6 and Table 2-7 list
command parameter limits. Note that each sense range requires three parameters: zero,
negative full scale, and positive full scale. Similarly, each source range requires four
parameters: two zero parameters, a positive full-scale parameter, and a negative full-scale
parameter.
For a more complete description of these commands, refer to Appendix B.

DATA?
Calibration subsystem.
Cal commands protected by password.
Unlock cal: changes password if cal is already unlocked.
(Default password: KI002400.)
Query number of times 2400 has been calibrated.
Save calibration data to EEPROM.*
Lock calibration, inhibit SAVE command operation.
Request cal lock status.
Program calibration year, month, day.
Query calibration year, month, day.
Program calibration due year, month, day.
Query calibration due year, month, day.
Calibrate active measure range. (See Table 2-6 parameters.)
Query measurement cal constants for active range.
Calibrate active source range. (See Table 2-7 parameters.)
Query source cal constants for active range.
*Calibration data will not be saved if:
1. Calibration was not unlocked with :CODE command.
2. Invalid data exists. (For example, cal step failed or was aborted.)
3. Incomplete number of cal steps were performed. (For example, omitting a negative full-scale step.)
